Miss. Code § 27-35-115
When the Department of Revenue has completed its examination of the recapitulations, and within thirty (30) days after the receipt of recapitulations from each of the counties of the state, it shall direct what action the county must take in order to comply with the provisions of Section 27-35-113. On the other hand, if the department finds that the assessment of any county or counties is reasonably equal and uniform with the assessment of other counties, and in proportion to the true value of the property and does not require an increase or decrease in the assessment of any class of property, in order to secure such equality and uniformity, the department, shall approve the assessment roll or rolls, or reproductions thereof, and direct the board of supervisors thereof, to have copies of the rolls made as required by law. Like determinations shall be made by the department with respect to the recapitulations of all the remaining counties as they are received by the department. The department shall send notice of the results of its examination of the recapitulation of the assessment rolls and the action taken in regard the recapitulation by United States mail to the president of the board of supervisors of the county whose recapitulation was examined.
